A transistor in a circuit can do many things. It can be used to amplify voltage signals, or current signals, create current and voltage sources, make buffers, and so on. Transistors also find a major use in logic circuits (ie, where signals can either be a '0' or a '1'), where they essentially act as a switch, and can be used to create inverters, AND gates, OR gates, and all sorts of useful components.
By itself, a transistor is a three-terminal device that can control the current going through two of its terminals through the voltage applied at the third terminal.
But there are many applications for a transistor in its many different configurations, which is why it is so important in modern electronic technology.
A transistor will either amplify a signal, or - more common in electronic circuits - work as a kind of switch, where one current can turn another current on or off.
They use transistor as the purpose to transfer the voltage
The importance of the Transistor was that it could amplify an electrical signal. It was thus an analog of the vacuum tube devices, and could take advantage of the circuit history and applications that had built up over the preceding 50 years.
Biasing is necessary in a transistor circuit to keep the transistor working. Without proper biasing, the circuit will fail

A transistor is a semiconductor(like many) that amplifies and switches electrical signals(electronic switch) in a circuit, it is used inside a circuit which requires switching without been manually operated.

A transistor is a small electronic device containing a semiconductor and having at least three electrical contacts, used in a circuit as an amplifier.
the function of an led is to give of light coming through an electrical circuit

This circuit can switch on and off light a fan or a radio etc;by the sound of a clap This circuit is constructed using basic electronic component like resistor transistor relay transformer capacitor .This circuit turns on light for the first clap . the light turns on till the next clap .for the next clap turns off this circuit works with 12v voltage . therefore a step-cown transformer 12v/300ma is employed. The working of the circuit is based on amplifying nature of the transistor . switching the nature of transistor and relay as an electronic switch.
